FRANK E. S EELEY, F BRIDG-EPORT, CONNECTICUT, ASSIG-NOR TO THE PERKINS ELEC- TRIO SWITCH MANUFACTURING COMPANY, OF BRIDGEPORT, CONNECTICUT, A
CORPORATION OF CONNECTICUT. I
ELECTRIC-LAMP SOCKET.
Specification of Letters Patent Patented Mar. 25, 1913.
Application filed December 23, 1909. Serial No. 534,683..
To all whom it may concern Be it known that I, FRANK E. SEELEY, a citizen of the United States of America, residing in the city of Bridgeport, in the county of Fairiield, in the State of Connecti I cut, haveinvented certain new and useful Improvements in Electric-Lamp Sockets, of
which the following is a specification.
a. sectional view on the line 1-1, Fig. 4, the
- the usual inclosing cap and shell being omitted; Fig. 2 is a sectional view on the line 2- 2, Fig. 4; Fig. 3 is an inner faceiview showing the lamp-receivin terminals; Fig. ,4 is a plan x iew showing the upper insulating block removed; Fig. 5 is an inner face view of the upper insulatingblock; Fig. 6 is a sectional view on the line 6-6, Fig. 4; Fig. 7 isa perspective view of the central contact for the lamp base; Fig. 8 is a perspective view of the supportingbracket for t e switch mechanism and the binding post connected therewith.
Although my invention may be applied to sockets in which the insulating body is in one piece, it is especially useful and I have shown it applied in the accompanyin drawing to the two-blockltype of socket orming the. subject of the Perkins Patent No. 626,927.
A is the upper block and B the lower block, which two blocks are heldtogether by the side-posts or brackets D and D Figs.
.1 and 4, with the aid of screws 10, 10, in-
. the lower block.
sorted through the back of the upper block,
the lamp-receiving screw shell S carried by The upper block has a central inner .re'- cess a to receive a part of the switch-mechanism and more particularly the spiral spring 13 and the upper part of the switchsupporting-frame F. The main part of this frame F is contained within a chamber or recess in theupper face of the lower block and is connected to 1t or has made in one or bracket and opposite ends of the contact plate,
with it the bracket D before mentioned, and
which has a screw 01 for the attachment of one of the .wire terminals. This binding post the switch mechanism thus occupy one chamber formed by recesses in the two blocks,-while the other binding post or bracket D which carries the binding screw 03 for the other wire terminal is contained in another chamber formed by recesses in the adjacent faces of the two blocks.
It will be seen that the binding screw cl is in electrical connection with the screw shell S by means of the securing screw 12,
whilethe screw 11,.which holds the lower" block and also the screw shell to the bracket D is insulated from the screw shell.
The switch spindleEpasses freely through slots 15, Fig. 8, in the two arms of the frame F and is held therein moval by lugs 16, (Figs. 2 and 4), punched up as usual from the spindle itself. The key spindle also passes through the switch block or cam G, being provided with projections 17, Fig. 2,- within the cam to actuate the latter as usual, with lost motion.
Upon the upper part of the cam bears. a plate 14 pressed down by the spring 13 so as to retain the block G ineither the vertical or horizontal position to which it may be turned. In the drawingI'have shown the block G as in its vertical position to close the circuit-. The block B has a central rectangular opening I) through it for the passageof the cam to enable the latter to come into contact with the central contact plate H, the
construction of which is best illustrated in Figs. 3 and 7 This contact plate liesbelow or on the inner face oftheinsulating disk from longitudinal re- 18, which rests again'st'the flange of the screw sh ll S and the plate H is secured in place by headed bolts-19, (Figs. 4 and 6), passing freely through openings in the lower "block B and secured by nuts 20 in recesses in the back of the block, Fig. 6. These securthrough openings in the which spring tongue h ing bolts 19 pass has bent up from it a against which the center contact or terminal I of the lamp base will make contact when the lamp is screwed into the socket. This spring tongue 7:. is formed originally in extension of the plate H. and joined thereto by supporting legs which straddle the perforated securing lug, so that when the tongue h is angled As shown in Fig. 2,
back over the plate free access to the bolt 19 passing through the securing lug, is afforded. the insulation disk has a central opening corresponding with the central opening'b in the block B for the passage of the cam G.
/ Bythe construction described I am able to get the parts of the socket within a smaller compass than usual.
I claim as. my invention:
1. In a key socket, the combination of a screw shell, and a key mechanism having a. contactcam with an insulating body to 'receive the key mechanism and having a central opening from the chamber containing the key' mechanism to within the screw shell, an insulating disk Within the screw shell,-also with an opening through it for the passage of the cam, and a contact plate for the cam held against the underside of said insulating disk.
2. In an electric lamp socket, a pair of insulating buttons and switch mechanism in- Gopies of this patent may be obtained for five cents each, by addressing closed between the same, said mechanism rying also a binding. screw, substantially as described.
3. In a device of the character described, a contact comprising a base perforated to receive a securing screw and an integral contact tongue bent over said base and having an opening at the bend to permit free access to the securing screw.
In testimony whereof I have signed my name to this specification, in the presence of two subscribing witnesses.
I FRANK E. SEELEY.
